title = "Equation of state of QCD at finite chemical potential from an alternative expansion scheme",
abstract = "The equation of state of Quantum Chromodynamics (QCD) at finite density is currently known only in a limited range in the baryon chemical potential µB. This is due to fundamental shortcomings of traditional methods such as Taylor expansion around µB = 0. In this contribution, we present an alternative scheme [1] that displays substantially improved convergence over the Taylor expansion method. We calculate the alternative expansion coefficients in the continuum, and show our results for the thermodynamic observables up to µB/T ≤ 3.5.",
